Question 1
Which statement correctly identifies a normal neonatal laboratory value?
Correct Answer:
Hemoglobin range of 12.7-18.6 g/dL
Explanation:
Neonatal lab values reflect transitional physiology after birth, especially the higher red cell mass and fetal hemoglobin. Hemoglobin in healthy newborns is typically higher than adult values, often in the mid-teens to the low twenties range. A range that includes 12.7 to 18.6 g/dL fits well with what many healthy newborns may have in the early neonatal period, so it represents a normal finding. A white blood cell count in the tens of thousands can occur, but the normal range for a healthy neonate is lower; counts as high as 50,000–60,000/µL are not considered a typical normal finding and may indicate stress or infection rather than a normal baseline. Neonatal glucose should be maintained above about 40 mg/dL; a value of 20–40 mg/dL would indicate hypoglycemia, which is not normal and requires assessment and intervention. The albumin/globulin ratio in healthy neonates is not typically this high; a ratio around 3.0–4.0 would be unusual and not considered a normal baseline. Thus, the statement describing a hemoglobin value in the neonatal range best aligns with normal neonatal laboratory findings.
Question 2
What is the most accurate way to get a temperature on an infant?
Correct Answer:
Skin
Explanation:
Infants need a temperature reading that best reflects core body temperature. Rectal thermometry provides the closest estimate of core temperature in this age group because the rectal area mirrors internal temperature more reliably than surface measurements, which are easily influenced by ambient conditions, movement, or recent feeding. Use a lubricated digital thermometer and insert just a small amount into the rectum with care to avoid injury, following safety guidelines. Axillary temperatures can be affected by room temperature and perspiration, making them less reliable for diagnosing fever in infants. Oral temperatures aren’t appropriate for infants due to cooperation and accuracy issues, and skin temperatures are too variable to reflect true core temperature.
Question 3
Which nondepolarizing neuromuscular blocker is commonly used for rapid sequence intubation due to rapid onset?
Correct Answer:
Rocuronium
Explanation:
Rapid sequence intubation relies on a neuromuscular blocker that takes effect quickly so the airway can be secured with minimal apnea. Among nondepolarizing options, rocuronium has the fastest onset, especially at higher RSI doses, producing intubating conditions in about a minute. That quick onset makes it the best choice for RSI compared with pancuronium (slower onset and longer duration), vecuronium (slower onset), and atracurium (moderate onset with potential histamine release). In short, rocuronium is favored for RSI because its rapid onset reliably achieves adequate relaxation for prompt intubation.
Question 4
What is the normal range for cardiac index (CI)?
Correct Answer:
2.5-5.0 L/min/m2
Explanation:
Cardiac index shows how well the heart pumps relative to body size, calculated as CO divided by body surface area. The normal range is about 2.5 to 5.0 L/min per square meter. This normalization lets us compare heart performance across different ages and sizes. Values below 2.5 suggest inadequate perfusion or reduced cardiac output for the body's needs, while values above 5.0 indicate a hyperdynamic state or excessively high output. Exact cutoffs can vary with age and measurement method, but 2.5–5.0 is the commonly cited normal range.
Question 5
Normal neonatal sodium range?
Correct Answer:
133-149
Explanation:
Normal sodium in a term neonate is about 133 to 149 mEq/L. This range reflects the still-maturing kidneys and the fluid shifts that occur after birth, with sodium helping to keep extracellular fluid and osmolality in balance. Values within 133–149 indicate what is expected for healthy newborns; when sodium drops below 133, hyponatremia can occur from excess free water or losses, and when it rises above 149, hypernatremia can result from dehydration or high-sodium fluids. Among the given options, 133–149 best matches the typical neonatal range. The other ranges either start too high or too low or extend beyond the usual neonatal limits, making them less appropriate representations of normal neonatal sodium.
